摘要:
A numerically controlled machine tool for machining a workpiece in accordance with a machining program as a checking mode and is operative to execute a plurality of commands including commands for controlling the movement of the tool. It comprises specifying means for specifying travel of the tool and means for stopping the movement of the tool after the tool has moved by said specified travel on a tool locus specified in the machining program. Moreover, means are provided for moving the tool by said specified travel on the locus of the machining program during the checking mode in order to perform a check.
摘要:
A numerical control unit for automatically machining a workpiece on the basis of a machining program, comprises a memory unit (32) for storing data input/output to the NC unit (1), and an editing unit (40) for editing data stored in the memory unit (32) adapted to edit data pertaining to a future machining job while the unit is performing a present machining job. There is provided a storage area storing history data relating to a plurality of previously made corrections, the history data being correctable.
摘要:
A numerical control system is provided for controlling a machine tool comprising control means (12) and an external portable storage means (1) for storing operation data. Read/write means (20) are provided for reading data from and writing data into the external storage means (1). A parameter data memory (80) is provided for storing parameters which can be changed by an operator. Such parameters include cutting program parameters or tool data. The control means (12) are adapted to manage the parameter data by assigning parameter names (81) and parameter dates of creation (82) to each parameter. The parameter names (81) and dates (82) are stored in a parameter data memory (80).
摘要:
A numerically controlled machine tool which allows the automatic generation of a restoring program for carrying out processing required for the resumption of an NC machining program to resume the execution of the NC machining program after the execution of the NC machining program has been stopped and interrupt processing has been performed. Specifically, even for nesting programs, when the machining program is re-executed from where it had stopped after the execution of the machining program has stopped and the operator has performed optional interrupt processing, the stop-time and re-execution-time machine statuses are compared to automatically generate the restoring program so that the machine status may be returned to the stop-time status, whereby the operator can perform the resumption processing of the machining program without any restrictions.
摘要:
A numerical control unit (NCU) (1) uses character codes to communicate with an external input/output apparatus (2). Further, internal NCU data is stored in an array format corresponding to a display format. Further, while one set of data is being executed by the NCU (1), another set may be corrected by the user. Further, some parts of program data may be specified in variables. Still further, memo data is provided to describe each piece of data. Finally, input program data is directly sent to a buffer where it is used to control a machining operation.
摘要:
A numerical control system for controlling a machine tool (14) including a control device (12, 13) for controlling the machine tool (14); external portable storage device (1) for storing data; a disabling device (22) for disabling the control device (12, 13); a read/write device (20), operable when the external portable storage device (1) is manually coupled thereto, for reading data from the external portable storage device (1) and for writing data to the external portable storage device (1); and a determining device for determining whether the external portable storage device is coupled to the read/write device (20). The disabling device (22) disables the control device (12, 13) when the determining device determines that the external portable storage devices (1) not coupled to the read/write device (20).
摘要:
A numerical control system for machining a workpiece including a reader (11) for reading a machining control program for the workpiece, a control device (12) for supplying a control signal to a machine tool (14) for the workpiece and a storage device (18,19) disposed internal or external to the control device, for storing a conversion table for converting a first character string read from the program into a second character string representing a command. The control device (12) operates in response to the reader (11) reading the first character string to supply the control signal to the machine tool in accordance with the command of the second character string. The second character string may represent, e.g., a delete command or a repeat instruction command.

A numerical control system for controlling a machine tool (14) including a control device (12, 13) for controlling the machine tool (14); external portable storage device (1) for storing data; a disabling device (22) for disabling the control device (12, 13); a read/write device (20), operable when the external portable storage device (1) is manually coupled thereto, for reading data from the external portable storage device (1) and for writing data to the external portable storage device (1); and a determining device for determining whether the external portable storage device is coupled to the read/write device (20). The disabling device (22) disables the control device (12, 13) when the determining device determines that the external portable storage devices (1) not coupled to the read/write device (20).
